Question 888342: a cellular phone manufacturer randomly selects 5 phones from every batch of 50 produced. If at least one of the phones is found to be defective, then each phone in the batch is tested individually. Find the probability the entire batch will need testing if the batch contains 8 defective phones Answer by oscargut(2103) (Show Source):
You can put this solution on YOUR website! P(at least one cellphone defective) = 1-P(no defective)
P(no defective) = (42C5)/(50C5) = 850668/2118760 = 0.4015
Answer: 0.5985
